Patented Dec. 20, 1932 UNITED STAT ES PATENT OFFICE? HENRY DOLIER, JR OFBRIDGEPOB'I, CONNECTICUT REVERSIBLE BRIDGE susrmvsron STRAP IApplication filed September 24,1930. seria nolmnsrq This inventionrelates to electrical outlet box bridge straps, and particularly tobridgestraps formedof a single piece, strong and durable to supportfixtures of great weight and readily adaptable to use in connection withordinary outlet boxes and a Wide variety of cover plates, canopies,etc., and providing the maximum of accessibility for the ready making ofthe electrical connections Figure III is an outlet box in section withwhich the suspension strap is operatively connected.

Figure IV shows the bridge suspension strap of Figure III in reverseposition.

Figure V shows a modified form of bridge suspension strap.

Proceeding in accordancewith the foregoing and with like referencesindicating similar elements inthe respective figures, 1 IS a bridgesuspension strap having end sections 2-2 lying in the same plane, withsections 33 extending respectively at anglesfrom sections 22, andanintermediate section 4 lying in the plane parallel to the plane of endsection 2-2'. Intermediate section 4 has an elongated or slotted opening5. The sides 6-6 of intermediate section 4 alongside open ing aredisposed substantially at right anto theend sections 22 and providedwith openings 7-7 to receive bolt 8 with which fixture suspension means9 projecting thru opening 5 is supportingly engaged.

End sections 22 are provided with slotted openings 10-10 by which thesuspension bridgestrap is secured by screws 11-11 of Figures II, III andIV to outlet box 12. The slotted openings 10 serving to accommodate theready assembly of the bridge suspension strap with outlet boxes havingdifierent dimensions Box 12, it will be noted,is pro-c vided withears-'13 having threaded openings to receive screws '11.

In Figure III, sections 33 and 4 of bridge suspension strap 1 projectinwardly of the box 12. Threaded link 9 projects thru slot 5 and bolt 8'passes'thru openings 77 of the strap and'through the threaded link thusconnecting-them operatively. From link 9 a fixture may be suspendedwhenv desired. A plate 14 having a suitable opening is passed over link9 and nut threadedly engaging with link 9 is turned up against the plate14: to secure the latter in position over the outlet box. j v I I I InFigure IV. the bridgestrap is secured to the outlet box as in FigureIII," except that sections 3-3 and 4 project outwardly of the box inwhich case canopy 14a projects over the outlet box and suspension strap.Thread ed link Qaand nut 15a serve to support canopy 14a, also thefixture may be suspended from link 9a as from link 9 of Figure III.

In Figure V, the suspension strap is shown, without sections 3-3 ofFigures I, II, III

and IV, the strap beingcformed substantially in a single plane buthaving sides 66 along opening 5 disposed at right angles to the body ofthe strap.

The function of the opening 5 is to receive fixture supporting meanswhereas two objects are achieved by turning sides 6-6 at right angles tothe body of the strap, namely great strength is added to the strap and aI ready means for engagement with the fixture support is provided. Thebridgestrap of Figure V may be used in connection with plates 14 orcanopy 14a and many other forms of box covers if desired.

-With the form of bridge suspension strap shown in Figures I, II, IIIand IV it will be readily observed that the central section of the strapmay be disposed within or without the box as the type of cover plate orcanopy varies and as will provide the greater convemence andaccessibility to supply wlres.

The manner of connecting the strap to the box remains the same in eitherform of use.

What I claim 1s:

1. A bridge suspension strap for electrical l outlet boxes, having acentrally disposed opening, the sides of the strap adjacent said openingbeing formed at right angles to the body of the strap and means throughthe sides formed at right angles to support a lighting fixture.

2. A bridge suspension strap for electrical outlet boxes, having acentrally disposed opening, the sides of the strap adjacent said openingbeing formed at right angles to the body of the strap, said sides beingprovided with means passing through the angle sides to engage fixturesupporting means.

3. A bridge suspension strap for electrical outlet boxes having acentrally disposed opening, the sides of the strap adjacent said openingbeing formed parallel to each other and at right angles to the body ofthe strap and provided with registering openings through the parallelsides to receive means from which a lighting fixture may be suspended.

4. A bridge suspension strap for electrical outlet boxes having acentrally disposed opening, the sides of the strap adjacent said openingbeing formed at right angles to the body of the strap and said rightangle sides provided with registering openings through which a means maybe projected engagingly with a. fixture supporting means projectedthrough said centrally disposed opening.

5. A reversible bridge strap with central section having elongatedopening, the sides of which are bent at right angles and parallel toeach other and means through the parallel sides for hanging support.

In testimony whereof I aflix my signature.
